Pinch grip type bottle-shaped container

Abstract

A pinch grip type bottle-shaped container (10) has opposed finger-receiving recesses (11) at sidewall regions of a container main body part, respectively, to thereby form a grip part (G) of the container (10), by the entire region including the recesses and a back surface region of the body part between the recesses. The container according to the invention is provided, at bottom surfaces of the recesses that can be touched and held (11), with multiple projections (14) projecting inwardly or outwardly of the container, thereby improving mold-releasability after the molding process.

Description

BACKGROUND ART

[0001] 1. Technical Field

[0002] The present invention relates to a bottle-shaped container, i.e., a so-called pinch grip type bottle-shaped container wherein the body part of the container main body is dividedly formed with finger-receiving recesses that can be used as a grip part for gripping the container.

[0003] 2. Related Art

[0004] Synthetic resin containers as represented by PET bottles are light in weight, easy to handle, and have transparency to exhibit a refined appearances comparable to glass containers, besides that they can be manufactured at low cost. Thus, such containers are widely used as containers for filling therein foods, beverages, cosmetics, medicines or the like.

[0005] There is a recent tendency to demand for reduction of the resin amount to be used per one container, from the standpoint of effective utilization of resources and reduction in amount of wastes. To cope with such a demand, there are used pinch grip type bottle-shaped containers w...

Embodiment Construction

[0014] In FIGS. 1 through 3, reference numeral 10 designates a pinch grip type bottle-shaped container of a kind widely used as one having a filling volume of 2.7 liters. Reference numerals 11 designate recesses formed in sidewall regions of the container main body part in mutually opposed orientations, respectively, and reference numeral 12 designates a pressure-reduction compensating panel provided in the back surface region between the recesses 11 for preventing shape deformation of the container as a result of pressure drop within the container. There is formed a grip part G for gripping the container, by the entire region from one recess 11 to the other recess 11, including these recesses themselves and the pressure-reduction compensating panel 2.

[0015] Each of the regions near the body part of the bottle-shaped container 10 is reinforced by three reinforcing ribs 13 which extend in parallel with each other along a circumferential direction of the body part. The grouped three ...
